'Short-circuit' found in ocean circulation

...lating Earth's climate. The findings show that much of the overturning circulation - how water moves and mixes vertically - around Antarctica takes place just around the tip of South America and in the small region in the Atlantic south of the Falklands, called the Scotia Sea. Co-author Prof Andre...

Researchers publish first marsupial genome sequence

DOE JGI sets 'gold standard' for metagenomic data analysis

...e belongs to which organism. In metagenomes, it's much more challenging, because you have sequences from many different organisms all mixed up, and moreover, you don't have enough sequence from each to capture an accurate picture of the entire community, so you only get a glimpse of the identities of mul...

Researchers attach genes to minichromosomes in maize

...ome is made of both centromeres and telomeres with much intervening DNA, a minichromosome contains only centromeres and telomeres, the end section of a chromosome, with little else. However, minichromosomes have the ability to accept the addition of new genes in subsequent experiments. Birchler said th...

Research says boiling broccoli ruins its anti-cancer properties

...earchers found that storage of fresh vegetables at much lower temperatures such as ?5 °C (much higher than for storage in a refrigerator at 4? °C) may cause significant loss of glucosinolates up to 33% by fracture of vegetable material during thawing. The researchers found that preparation of Brassica ...

From the deep -- Researchers find new species of sea anemone

...aquatic creatures uses that sulfur to make energy, much like plants convert light into energy." Daly doesn't know much about A. pearseae beyond its physical description. She and Gusmão aren't sure how old the creatures ...

Herpes infection may be symbiotic, help beat back some bacteria

...ed that several strains of herpes viruses found in much of the human population remain symptom-free throughout the host's lifetime. "Our results suggest that we should look at whether humans receive similar advantages from these and other chronic infections that do not cause active disease," says senior...

Scientists seek useful traits in wild cottons

Scientists discover new life in the Antarctic deep sea

...eeper parts of the Southern Ocean - the source for much of the deep water in the world ocean ?are likely to be related to animals living in both the adjacent shallower waters and in other parts of the deep ocean. A key question for scientists is whether shallow water species colonised the deep ocean o...

Gene thought to assist chemo may help cancer thrive

...mors had a mutated p53 gene that didn't work had a much better survival rate than those who had normal p53. In the study, researchers took malignant and benign ovarian tumors straight from the operating room and compared their gene expression profiles. Some of the cancer patients had been treated with ...

DNA analysis suggests under-reported kills of threatened whales

A new portable biosensor detects traces of contaminants in food more quickly and cheaply

It is currently classified as Endangered on the IUCN Red List of Threatened Species, the same status as tigers and pandas. Threats to its existence include over-harvesting by hunters due to its size and...

Study of protein folds offers insight into metabolic evolution

...ual enzymes ?are composed of both very ancient and much more recent protein architectures. "This mosaic is telling you that the new enzymes and old enzymes are together performing side by side," Caetano-Anollés said. "In some cases in the same protein you have old domains and new domains working togeth...

Discovery of 'master switch' for the communication process between chloroplast and nuclei of plants

...hrough this one particular route. "Now we are in much better shape in solving the question of generating plants that can use marginal water, or marginal soil, and do so in a way that the plant won’t completely suppress its normal metabolisms and activate all of its stress metabolisms when faced with a l...

City ants take the heat

Now, an international team of biologists, led by Michael Angilletta of Indiana State University, has shown that city animals have been affected by urban ...
